Specification of Letters Patent.

Patented Jan; 5, 1915.

Application filed July 5, 1912- Serial No. 707,802L

i 0 all whom it may concern:-

Be it known that L'VVILLIAM H. Nnnnnearn, a citizenlof the United States. residing at Pcndleton, in the county of Umatilla, State of ()regon, have invented certain new and useful Improvements in Traction- Wheels, of which the following is a specification.

This invention relates to improvements in traction wheels which is principally designed for either road or agricultural work. An object of the invention is to provide an improved tractive wheel Withthe coupling so arranged as to obtain the necessary, low speed transmission with a resulting maximum gear leverage.

A further object of the invention is to provide an improved form of tractive wheel whigh, by reason of the improved construction; can be made much lighter than hereto-- tion wheel, illustrated more fully in Figs. 1

and 2, the same consists of avcenter structure which may comprise a hub 35 and spokes 36, and a tractive tread which is indicated as a whole at 37. As shown the tread is made up of a plurality of parallel rings 38 and 39, the former being connected with the spokes 36 which latter converge inwardly toward their outer ends. The connection of the spokes 36 with the rings 38 is indicated at a0 and the'inner ends of the spokes 36 are connected to flanged extensions ii on the hub 35.

'Tractive elements 42 are disposed about the periphery of the wheel and are arranged in spaced relation with respect to each other sons to provide through open spaces therebetween whereby clogging of field soil or road mudis effectively prevented, the open spaces between said elements having no bases. I may conveniently dispose the ele ments d2 transversely of the plane of the .outer ring 39. The rack :26 is connected with the tractive elements 42 by U-shaped members 44. In order to counteract and overcome any torsional or twisting strains imposed by the application. of driving power to the sides of the wheel 3, I desirably brace the same by laterally and preferably dingo nally disposed brace members 45 and i6, which are riveted or otherwise suitably secured'to the rings 38 and 39, as illustr: ted.

lVhile l have herein shown and described one specific form of my invention it will be understood that I do not wish to be limited thereto except for such limitations as the claims may import.

I claim:

1. A traction wheel comprising in combination, a center structure and a tread therefor, a rack near one side edge and within said tread, and lateral and diagonal braces for said wheel counteracting side draft.

2. A traction wheel comprising a hub structure, a-plurality of ring members s11r-- rounding said structure, spaced traction elements carried entirely on the outside of said rings, and U-shaped braces for connecting adjacent elements.

3. A traction wheel comprising in combination, a central hub provided at its end with inwardly inclined integral flanges, a plurality of rings surrounding said hub. the outer surfaces of said rings lying on a given cylindrical surface, spaced traction members carried on the outer surfaces of said rings and having'their outer surfaces lying srbstantially in a given cylindrical surface. inwardly-inclined spoke members connecting said flanges with two of said rings. and inclined brace members connecting said ring, said brace members forming acute angles with the planes of said rings.

4. A traction wheel comprising in combination, a central hub provided with inclined integral flanges, a plurality of rings surrounding said hub, the outer surlaccs of said rings lying on a given cylindrical surface. spaced traction members carried on the outer surfaces of said rings and having their outer surfaces lying substantially in a given cylindrical surface, inclined spoke members connecting said flanges with two of said rings,

and inclined brace members connecting said rings, said brace members forming acute angles with the planes of said rings, and U- shaped braces carried on the outer surfaces of said ring members intermediate said traction members and attached to saidtraction members.

5. A traction wheel comprising in combination, a central hub provided with inclined integral flanges, a plurality of rings surrounding said hub, the outer. surfaces of 1 said rings lying on a given cylindrical surface, spaced traction members carried on the outer surfaces of said rings and having them outer surfaces lylng substantially 1n a given cylindrical surface, inclined spoke members connecting said flanges with two of said rings, and inclined brace members connecting said rings, said brace members forming acute angles with the planes of said rings, and U-shaped braces carried on the outer surfaces of said ringmembers intermediate said traction members and attached to said traction members, and a rack carried with said traction members at one edge thereof, and heavy U-shaped members resting on the outer surface of said rack intermediate said traction members.

In testimony whereof I aifixmy signature in presence of two witnesses.
